System Overview
Nofence is the pioneer of commercial virtual fencing for livestock. Farmers draw custom grazing paddocks on a mobile app. As livestock approach the border, the collar emits a rising audio scale. If the animal turns back, the tone stops; if it continues, a low-energy pulse (0.1 - 0.3 Joules) is delivered. Animals comply 98% of the time based on audio cues alone.
